Edited by the Manufacturingtalk editorial team Jan 20, 2005

As part of a line upgrade at a UK automotive manufacturing plant, 145 resistance weld timers - remotely settable through robot control panels - have been installed.

Toyota Manufacturing UK has recently taken delivery of 145 resistance weld timers from Dengensha Europe, based in Shenstone, Staffordshire and the European subsidiary of the Japanese resistance welding equipment manufacturer and supplier Dengensha Manufacturing Co These controls were ordered in July and are being used as part of a line upgrade at Toyota's manufacturing facilities in Burnaston, Derby, UK.

The order comprised 66 off RWC-9000 single phase AC resistance spot welding timers and 79 off RWC-9100 DC inverter type resistance spot welding timers.

Both are lightweight and compact, wall mounted, integrated weld timers/contactors with 32-bit microcomputers.

Programming on these timer/contactors is carried out by remote setting via the robot control panel.

The I/O status is displayed on a 7-segment LED.

The RWC 9100 input signals include start, leak detection, error reset, weld/test and weld permission, whilst the output signals are end of welding and contact detection, whilst the RWC-9000 has a constant current control, monitoring and error detection functions.

John Mason, Managing Director at Dengensha Europe said: "Dengensha worldwide is a supplier to Toyota, have supplied equipment for their manufacturing plants around the World.

At Dengensha Europe we supply Toyota plants throughout Europe with complete product back up and service where required.
